It is a common practice in textile mills toidentify filling yarn by marking the bobbins with crayon or chalkto indicate different types and counts of the yarn and also to identify the machine or department in which the yarn is processed or handled. Usually, the operator of the machine marks the yarn on the bobbin by drawing a piece of chalk or crayon over the surface of the bobbin, but this operation has certain disadvantages as it is liable to cause the chalk dust'to in machine to interfere with its proper functioning.

The practice of marking the bobbins as now generally used is for the purpose of preventing mixed counts of filling yarn going to the same loom and becoming incorporated in the fabric. In such case the difference in the size or count of the filling does not become evident until the cloth is woven and therefore it results in spoilage or seconds in the product of the mill. When the bobbins are properly marked the weaver can discover if mixed yarn is furnished to the weave room and place the responsibility in the winding room or other department of the mill where the yarn was pr'ocessed'or handled. In other instances, by applying several distinguishing marks to the yarn on the bobbin its progress from the source can be followed and when poor or imperfect trate into the mechanism of the.

Another object of'the invention is to provide bobbin-identifying means which may be employed as an attachment on winding machines in which the bobbins are dolled either manually or automatically upon completion of the winding.

Another object of the invention is to provide means incorporated in an automatic winding machine for marking the indicia at the completion of the winding before they are defied from the machine.

bobbins reach the weave room they can be traced to the machine in which they were wound or to the department in which the yarn was processed. In some cases different types or counts of yarn are wound on difl'erent spindles of the same machine and the bobbins may become mixed through carelessness of the operator, as by the dropping of bobbins on the fioor or by incomplete emptying of the collecting boxes for one type of yarn before bobbins of another type are placed therein.

Most mills handlemore than one count of yarn atthe same time and as the counts must be kept separate it is an object of the present invention 1 the dye liquid; and

- a Another object of the invention is to provide a device which may be applied to winding machines to mark'the bobbins produced: therein with different colors applied by means fed from reservoirs containing fugitive ink or dye liquid.

Further objects of the invention in the following specification-which describes one form of construction of automatic bobbinidentifying means as illustrated by the accompanying drawing. f In the-drawing: v Fig. 1 is a side elevation of the-essential mechanism of a bobbin-wlnder showing means for marking the yarn on the bobbin by traversing stylographic-marking devices along its side withelectrically-controlled means for operating the same;

Fig. 2, is an enlarged end-view of the bobbin showing the series of styli or feeding means for Fig. 3 is an enlarged plan view ofa portion of the device showing the movable slide or. element which traverses the marking device along the side of the bobbin as it is held in connection with the winding spindle.

While the present invention may beapplied to use with either manually-operated or automatic winding machines, it is herein described and illustrated in connection with. a'machine of the type disclosed in United States Letters Patent No. 2,257,651, dated September 30, 1941, and No. 2,302,715, dated November 24, 1942. The .machines illustrated in these prior patents are completely automatic for donning empty cores or yarn-carriers, winding the yarn thereon, and doffing the bobbins as they are completed. It is therefore desirable that machines of this type bobbins with identifying a are set forth matic fllling-changms hem after they have been delivered therefrom. On the other hand, it is to be understood that the present invention is not limited to use with automatic winding machines, but may be applied to other types. of

winders for marking the bobblns'before they are dofled.

' Referring to the drawing, in Fig. 1 the frame or casing of the winding machine is indicated at 2 and. projecting from bearings therein is a retary winding spindle 8 at the end of which is a cup-shaped member I for receiving the head h of a wooden core or bobbin 1) such as used in autolooms. The opposite or tip end of the bobbin b is held in a similar recessed member 5 on a spindle 8 mounted free to rotate in a bearing sleeve 1 supported by a suitable bracket, not herein shown, attached to the side of the machine frame 2. In the type of mathe e pw curlers 4 doifed bobbin, attaching the end of the yarn to returning the thread-guide to initial winding position, and again starting the winding operation. The automatically-operated mechanism for performing these functions is described in the prior patents before mentioned and is not referred to specifically herein as it forms chine herein illustrated the yarn 1! is wound on the core or wooden bobbin b by means of a thread-guide it which has a relative traversing motion axially of the bobbin and is progressively advanced longitudinally thereof to deposit the yarn lap at their forward ends. In this way the bobbin grows by longitudinal extension, being formed with a conical'base, a cylindrical body portion and a tapered or conical tip end.

The thread-guide I0 is carried on a reciprocable traverse-rod I! mounted to slide longitudinally in a bearing in the frame or casing 2. The traverse-rod it is reciprocated longitudinally in its bearing by a suitable cam or similar means enclosed within the frame or casing 2 of the machine, but not herein illustrated assuch traversing mechanism is well known to those versed in the art. The yarny delivers from its source of supply, supported above the machine but not herein shown, and feeds to the bobbin through an eyelet I! in the thread-guide ill. C onnected to the thread-guide i0 is a rotatable contact-diskor traverse-wheel 20 mounted on a sleeve-like nut 2| which is interiorly threaded to engage the screw-threads 22 on the traverse-rod It. It will be understood that the thread-guide III is positioned adjacent the rearward or butt end of the yam-carrier or wooden bobbin b at the start of the winding and the traverse-wheel 20 is so related thereto that each time the guide makes a return stroke to the left, as viewed in Fig. 1,

in courses of cross-wound coils which overon the yarn when it is woven into the cloth, but

no part of the present invention.

The wound bobbins may be marked with several diflerent colors, for example red, yellow and green, to indicate the size or count of the yarn and other particulars such as the department in which the yarn was spun or processed, or in other cases the particular machine in which the bobbins were wound. The colored markings remain when the fabric is later processed or finished, the dye, being fugitive, will disappear on treatment with water or other liquids.

Figs. 1 to 3, inclusive, illustrate automaticallyoperated mechanism for applying identification indicia to the bobbins before they are doifed or removed from the winding spindles, this mechanism comprising a sliding or traveling element for carrying the marking device and means for traversing it longitudinally of the bobbin to apply the indicia thereto. Referring to U. 8. Patent No. 2,302,715, mentioned above, the movable yarn-retriever described and illustrated therein provides a convenient means for moving the marking device along the length of the bobbin. 1n the machine of this patent the yarn-retriever 35, shown in thepresent drawings, is slidable along a rod 38 and provided with a doublepronged hook 81 which passes in under the thread-guide it when the latter is at the tip end of the bobbin to take a loop of the yarn 1 therefrom and carry it back toward the spindle-cup 4 to place it thereacross for attachment to an empty bobbin when the latter is donned.

The yarn-retriever 35 is actuated at the completion of winding a bobbin B to cause it'to he slid along the rod 36 from the position shown by full lines to that indicated by dash lines in Fig. 1. The means for actuating the yarn-retriever may comprise a series of levers operated by an electrothe periphery of the wheel will contact the yarn a part of a rotation to feed the guide forward to a slight extent along the traverse-rod ll. This method of advancin the layers of winding along patents referred to above and is well known to those versed in the art. r

At the completion of the bobbin the. threadguide It will be positioned at the forward or tip end of the bobbin when at the furthermost limit of its forward stroke and at this point the guide, or a. part connected therewith, engages a stop or abutment to move the latter to cause actuation of the stopping mechanism of the machine; this mechanism being employed generally in machines which require manual dofling and donning. In automatic machines such as described in the pat ents referred to above, the completion of the bobbin eflects initiation of the operation of means for dofling the wound bobbin, donning an empty core or yarn-carrier, severing the yarn from the wound on the bobbin to turn the nut 2| through magnet 38. Pivoted at as to a bracket 40 supported from the machine frame 2 is a lever 4| having its lower end connected to the yarnretriever or slide 35 by means of a slot 42 engaged by a pin or stud 43 fastened to the slide. A link 46 pivotally connected to the lever H at one end is similarly joined at its opposite end to a bell-crank lever 48 pivoted at 41 on the bracket MI. The lower arm ll of the bell-crank 48: is-

connected by a link .42 to a second bell-crank ill therebelow pivoted at ii on a fixed support represented at 8 in Fig. 1 of the drawing. The per arm of the bell-crank 50 is pivotally connected to a link "52 which is similarly joined to the endof a plunger-armature 55 which is slidable by energization of the electromagnet 38. A helical spring 56 fastened to theupper arm of the bell-crank 50, at one end and anchored at 51V to the machine frame! normally tends to maintain the bell-crank illustrated in' Fig. 1 with the bell-crank 48 rocked to hold the yarn-retriever or slide 35 outwardly beyond the end of the winding bobbin B. In the machine ofthe prior Patent Noi 2,302,715 the electromagnet or solenoid 38' is energized by the closing of a switch which is operated automatically upon completion .of the winding of the bobbin; suitable means for. this purpose being illustrated and described in said 50 in the positionpatent. Upon energization of the solenoid 38, its armature 55 is attracted to draw it to the right, as viewed in Fig. 1, thereby causing the bell-crank 50 to beoperated to slide the-link 49 upwardly and rock the bell-crank 46 in counterclockwise direction. The lever 46 is thus caused to move the link 45 to rock the lever 41 and slide the yarn-retriever 35 from the position illustrated in full lines to that indicated by dash lines in Fig. 1.

The yarn-retriever or movable element 35 is employed as a means for marking the bobbin .by forming it with or attaching a part thereto constructed as a support for a plurality of styli or similar devices for applying colored indicia to the yarn on the bobbin B. As shown in Figs. 1, 2 and 3, an angular bracket or support 60 is attached to the rearward sid of the hook 31 carried by the retriever or slide 35 by means of screws 62 to serve as a support for a plurality of vials 63 adapted to contain the fugitive ink or dye liquid f. The vials 63 are clamped to the bracket 60 by means of a fluted strap 64 fastened thereto by screws 65, as shown most clearly in Fig. l, in position one above another with their mouths or openings upright, see Fig. 2.- Each stylus has a small tubular nozzle 66 projecting, forwardly therefrom with one end dipping into the liquid f and its opposite end arranged in position to contact the side of the bobbin B, whereby capillary attraction will cause the ink or liquid dye to feed through the nozzle and be applied to the yarn on the bobbin as the yarnretrieveror slide 35 is moved longitudinally of the. bobbin to the position indicated by dash lines in Fig. 1. I

The method of operation of the present embodiment of the invention is explained as follows: At the completion of winding the bobbin B the solenoid 38 is energized through the means of an automatically-operated switch in the electrical circuit to cause its armature 55 to operate through the link 52, bell-crank 50, link 49, bell-crank 46 and link '45 to rock the lever 4| and slide the yarn-retriever 35 toward the left. At this juncture the thread-guide I0 is at the outer or finishing end of the bobbin B, as shown in Fig. 1, and the hook 31 on the yarn-retriever will he slid under the guide to cause it to engage the yarn y and extend a loop toward the .left. As the yarn-retriever 35 slides along the side of the bobbin B the nozzles 66 make contact with the-yarn thereon to apply a series of colored lines or markings thereto. After this operation has been completed the spindle-cup 4 is withdrawn to release the bobbin to doff it from the machine.

While this automatically-operated means for marking the yarn on the bobbin before it is removed from the machine is shown in connection with the electrically-actuated yarn-retriever disclosed in the patent last referred to, it is to be understood that the invention is not limited to this form of construction of. the device as the marking device might be embodied in any movable part of the winding machine and actuated either manually or automatically before the bobbin is dofl'ed, either manually or automatically, the only requirement being to provide relative movement between the bobbin and the 6 marking means. the marking liquid might be dispensed with and chalk or crayons employed in their place.

It will be observed from the foregoing specification that the present invention provides means for applying identifying indicia to the yarn on filling bobbins or other forms of packages whereby to indicate the character of the yarn and its source of manufacture. While the device is herein shown as embodied in a preferred form of construction, it is to be understood that various modification may be made in the structure and arrangement of the parts of the device and the manner of applying it to use without departing from the spirit or scope of the invention. Therefore, without limiting myself in this respect, I claim:

1. In a winding or like machine, means for packaging yarn on the machine, an element movable longitudinally of the package, and means carried by said element and adapted to contact the yarn on the package to apply identifying indicia thereto.
